Not a bug? There is an option in app.ini to set ssh.minimum_key_sizes also for ED25519. If ED25519 is not supported it's a confusing option in app.ini

Hard to say, it has some support for it in code but have to check if this is bug or not fully supported

Pretty sure this is because OpenSSH on CentOS 6 is too old to support ED25519 keys.
